Hey guys hope everybody has had a great holiday. I have been busy with family and haven't been able to work on the truck much. But I was able to break away a little today and have come across some thing I need some advice on. I have one of my porterbuilt notches fitted to the frame loosely bolted working off a plumbob and center line. I am on the other side and have done the same thing and before I drilled and bolted I took some measurements off the front and back of the notch to the rear of the frame and I am 3/16's off from one to the other but dead on my center line?? Any suggestions...

Check out Rusbuilt's "Darcy" build thread. He had the same issue. As long as your rearend isn't making contact with the notch you should be fine. I only say that because of the various post I have read that mention the same issue your having with your notch.

Subscribing to see your progress!

Also I have been measuring various body mounts from one side to the other and the drivers side mounts are setting back an 1/8 more than the passenger side .. and the drivers side notch is the one I am trying to get figured out now.. frame is not damaged either.. idk. I guess I will be calling PB tomorrow and see what they say..

There are several post about frame variables and tolerances and what's acceptable without having to modify any of the frame to make your $$$ Porterbuilt parts fit. I'll see if I can pull some up for you.

Here you go Moose, this might help you get started.

Thanks Rus! You have been a tremendous help so far!

[Rusbuilt]

Its my pleasure sir! Keep us updated.

Well not much progress I have made this weekend.. I filled some holes in the frame and got one of my notches lined up and bolted, then ran into what could possibly be a problem when I went to do the other side.. Holding off til I can call Porter Built tomorrow and see what I am doing wrong.. here are a few pics

[sduckworth13]

The good news is that you have not cut the frame if you do have a issue, do the step notches measure equal length. The notch on the drivers side looks wider in the area where the axle sits in between. Maybe a optical illusion, I hope so.

Look at pics #63,#69.
Optical illusion on #83.
I’ve never installed one of these notches but I’d measure, measure, measure. And measure again.
You’ll get it.

Before you weld it all permanent like you might wanna stick all the rest of the kit together to make sure things jive together.

Lookin Good Man!

Ok guys I have a little update for you, I worked long into the night, and got the notches within an 1/8 of an inch of being parallel of each other measuring from the side to the back of the frame, but they where dead on square. This morning I pm'd Nate at Porter Built to see if he had any insight on my conundrum.. He assured me that an 1/8" was well within tolerance and that I could move forward with out worry. Thank you guys for all the suggestions, links and words of encouragement.. Also thanks to Nate for helping with everything its nice to have a company that stands behind and offers great support for there products!

Now as soon as I get done with this pesky thing called work, I can get back home and finish my notches..

[sduckworth13]

Good to hear you are at ease now with the setup, it would have bother me a bit too until I got concrete confirmation that the measurements not to far off from what's acceptable. Looking forward to seeing the rest of your build, good luck.

Hey thanks Scott! This is my first major frame altering build so it is a little nerve wrecking. That whole measure twice cut once thing has never been more true.. I guess in this case it's more like measure twice and if you're still not sure call someone who has been there done that...

Hey guys here is a little update for everyone. Last couple of weeks have been basically a scavenger hunt for parts. Finally found a late model 14bff from a dually, got it and striped all the brackets off also bought and received my perches and power steering plate from Captainfab. Gotta say these are awesome, craftsmanship is spot on great! Anyway got everything in and started mock up of the old axle to get a degree to set my new axle too. Here are some pictures.

[moose1008]

Here are a few more...

[rwade]

How will you attach your rear axle to the control arm? Isn't the 1 ton axle a bigger diameter? Will a bigger (diameter) U bolt fit in the control arm. Thanks for any info

Wade

I got the idea from another board member lostmy65 he has done a whole how on installing a 14bff and according to him and Captianfab it is tight on the u bolts but they will fit. I will definitely post more pic's as soon as my lowering blocks and u bolts come in and I get everything tacked in place.

[rwade]

Please do, I'll be working on the same thing in a few months. Thank you.
